• r23 = 1 for boiler use on system only (priority of resistor intervention);
• r23 = 2 for boiler use only in DHW mode (priority intervention of the heaters);
• r23 = 3 for boiler use in DHW and on system (priority intervention of resistors);
• r23 = 4 for boiler use only in system mode with priority;
• r23 = 5 for boiler use only in DHW mode with priority;
• r23 = 6 for boiler use in DHW mode and on system with priority;
Define the boiler equipment by setting parameter r32:
• r32 = 0 for boiler without circulator with thermoregulation charged to the heat pump;
• r32 = 1 for boiler with autonomous circulator with thermoregulation charged to the heat pump;
• r32 = 2 for boiler without circulator with autonomous thermoregulation;
• r32 = 3 for boiler equipped with circulator with autonomous thermoregulation.

21.7 LOGIC OF INTEGRATION HEATERS AND/OR BOILER IN JOINT OPERATION OR IN SUB -
STITUTION OF THE HEAT PUMP COMPRESSOR
The auxiliary parts that can be used for joint or for operation in substitution are:
• boiler
• system integration resistor
• domestic hot water integration resistor
The parameters to be considered for adjusting this operating logic are:
• r22 = set for joint operation with heat pump priority
• r28 = set for joint operation with priority of auxiliary units
• r08 = set for replacement operation
Considering the heating and/or DHW operating modes, there are 4 operating areas:

temp.
If it is necessary to change the values of the parameters, the formula r22 ≥ r28 ≥ r08 must be followed.
Setting r22 = r28 it is possible to eliminate the zone relative to joint operation 1st band; by setting r28 = r08 it is possible to eliminate the zone
relative to joint operation 2nd band; by setting r22 = r28 = r08 it is possible to eliminate both bands relative to joint operation.
The intervention priorities of the auxiliary heaters are defined by parameters r14, r20, r23, r24 (as described above).
